The challenge
Skødstrupbakken is listed as a sustainable ward, but like many other photovoltaic installations, the green power is typically produced in the middle of the day -- when residents are not at home to use it. Without a battery, large amounts of energy are wasted and it has to be bought back expensively from the electricity grid later when residents are home from work and peak loads hit.
The solution
AlmenBo Aarhus integrated the battery solution already during the construction phase, and with the support of the residents, a VisBlue flow battery was installed. The battery stores the solar energy and makes it available when consumption is highest — in the evening. It increases the utilisation of photovoltaics, ensures stable electricity prices and supports the housing association's aspirations for sustainability and safety.
“New construction should be born with solar cells and batteries. This is the way forward,”
— Pia Mouritsen, Chairman of the Board of Skødstrupbakken
The result
The hybrid system enables Skødstrupbakken to use a greater proportion of self-generated power — without rent increases. It creates both economic and environmental value, and residents are actively involved in driving the green transition into practice. With the local collaboration between VisBlue and Risskov Teknik & Solar, Skødstrupbakken is an example of how public housing associations can think about sustainability and energy flexibility from the start.
